Ever wondered how Megumin joined Kazuma or what her life was like before she joined Kazuma's team, well this anime has the answers and yes we get to see YunYun, Wiz and some other characters that are references to the Konosuba series and her life before is also hilarious, it is about her learning one spell and that is the legendary EXPLOSION spell that she witnessed an adventurer used back when she was a kid and saw an adventurer save her from monsters, we also got to see YunYun too and I mean more of YunYun as we didn't see her a lot and there are hilarious scenes too, would recommend watching Konosuba before this to get the character references though.
